Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 3511-2008 "Vulcanized rubber or thermoplastic rubber weatherability", compared with GB/T 3511-2008, the main
The technical changes required are as follows.
--- Revised the terms and definitions of "comparisons" (see 3.1,.2008 edition 3.1);
--- Added "Recommended to use one or more of the weathering reference materials described in Appendix A as an alignment in the exposure test"
Terms (see Chapter 5, Chapter 6);
--- Added normative reference document "ISO 18314-1 Analytical Colorimetric Method Part 1. Practical Color Determination" (see Chapter 2);
--- Added Appendix A; Adjusted Appendix A of the.2008 edition to Appendix B;
--- Add a "compression deformation" test project in Appendix B;
--- Added "References";
--- Removed the normative reference documents "GB/T 11186.1, GB/T 11186.2 and GB/T 11186.3" (see Chapter 2, see.2008
Chapter 2 of the edition).
This standard uses the translation method equivalent to ISO 4665.2016 "Vulcanized rubber or thermoplastic rubber weatherability".

introduction
A variety of different exposure methods can be used to obtain the effects of environmental factors (eg, light, heat, and water) on rubber. Each method
They all have their special uses and relationships. As a guide and guidance, the test methods for natural exposure and artificial climate can be based on ISO 877-1 and
ISO 4892-1. The ozone crack resistance exposure test method can be based on ISO 1431-1. Standard method basis for climate exposure testing of plastic materials
This applies to rubber materials, so the equipment and procedures of this standard relate to national standards related to plastics.
The procedure for determining the change in performance is preferably to use the same exposure conditions and the results are expressed in the same manner. Related procedures in this
There are detailed regulations in the standard.
Climate exposure can alter the properties of materials, especially on the surface of materials. Methods for determining performance changes should be considered, for example,
The important properties of the material used and the performance degradation may be concentrated on the surface of the situation. The method chosen should be able to guarantee
Testing of important performance changes in inter-applications is within a sufficiently precise range, so that the corresponding performance changes are judged on a meaningful basis.
Vulcanized rubber or thermoplastic rubber weatherability
Caution - Personnel using this standard should be familiar with the procedures of the formal laboratory. This standard does not indicate all possible security questions.
question. It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the conditions set by the relevant national regulations.
Attention - some of the steps in this standard may involve the use or production of materials or waste generated, causing harm to the local environment,
After the test, it should be safely disposed and disposed of according to the corresponding documents.
1 Scope
This standard specifies the change of color, appearance and physical properties of vulcanized rubber or thermoplastic rubber after exposure to natural or artificial climate.
Test method.
This standard applies to the determination of weatherability of vulcanized rubber and thermoplastic rubber.
